Nine species of avian landlubbers
The ostrich is the biggest flightless bird. Long, downy neck, black, brown, or grey body, white or buff tail based on sex and subspecies. Reddish-pink skin, broad neck, and long legs with 2 toes.
Emus are ostrich-sized. Six-foot-three. Their blue necks have black whisps. Black-tipped brown feathers. 3-toed feet. Omnivorous emus prefer grasses and flowers.
Three cassowaries seem different. Wedge-shaped bodies, dark feathers, and a blue casque. Casque size determines species. Cassowaries' droppings reseed rainforests.
Chicken-sized flightless birds. Vestigial wings and no tail. Long, delicate bill, 3 feet. Other senses compensate for poor eyesight. Specific colour.
Rheas resemble ostriches, but are smaller and have brown plumage. Their huge wings let them sprint faster. Rheas are South America's largest birds at 5 ft.
The cormorant's wings are short. Brown or black feathers, blue eyes, hook beak. These birds dry off after diving for fish and eels because their feathers aren't waterproof.
The Kakapo can't fly. Silky feathers let non-flying birds blend in. Grass-dwelling parrot. Moss-green feathers, weight gain. It's a good climber and eater.
Their diet is specialised. Killifish make about 95% of their diet. This grebe has head plumes. Yellow bill, white throat patch. It eats fish and is a skilled diver.
Men incubate a single egg for two months until the mother returns. Each takes turns feeding it until it can feed itself. They walk erect with flipper-like wings.
